About this 0.9ct lab-grown cushion diamond

This 0.9ct lab-grown cushion sits in the just-under-one-carat band, graded D colour (colourless) and SI1 clarity (slightly-included), with a very-good cut grade and certified by IGI LG569304118 or 569304118. Listed at 4 retailers as of October 31, 2026, with prices from €441 to €609, a €167 spread on the same certified stone. Kay Jewelers lists it at €609. Cut grade matters more than carat or clarity for visible brilliance. If you can shift budget toward an Excellent or Ideal cut, do it before chasing higher colour or clarity.
